Sažetak
X-ray excited luminescence and X-ray irradiation (10 - 3240 Gy) effect on the optical absorp-tion spectra of CdS_1-xSe_x nanocrystals in borosilicate matrix are studied. The parameters of the luminescence bands are analyzed with the account of the luminescence of the host matrix itself. The observed smearing of quantum-size-related maxima and absorption edge blue shift with the irradiation dose increase are related to the X-ray ionization of the nanocrystals with charge-carrier transfer between the nanocrystals and the host matrix. The radiation-induced changes completely vanish at post-irradiation annealing to 575 K.
